title: A synergistic increase in Bacillus subtilis 168 transformation produced by the presence of heterologous W23 DNA.
abstract: Transformations utilizing a 168-like recipient and mixtures of homologous and heterologous DNA lead to an unexpected increase in the number of transformants when the two DNAs are in equal concentration. The absolute requirement for native heterologous DNA to produce the effect was demonstrated. The increase may be due to a helping effect analogous to that found in Streptococcus.
